HUGH WALLACE, OF RICHMOND, OHIO.

CA R-COUPLING.

SPECIFICATION forming part of Letters Patent No. 340,261, dated April 20, 1886.

Application filed February 15. 1886.

To all whom it may concern.-

Be it known that 1, HUGE WALLAoE, a citizen of the United States, residing at Rich- I mond, in the county of Jefferson and State of Ohio, have invented a new and useful Improvement in Car-Couplings, of which the fol- I lowing is a specification, reference being had to the accompanying drawings.

My invention relates to an improvement in car-couplings; and it consists in the peculiar construction and combination of devices that will be more fully set forth hereinafter, and l particularly pointed out in the claims.

In the drawings, Figure 1 is an elevation, l partly in section, of a car-coupling embodying my invention. Fig. 2 is a front elevation of the same, partly in section.

A represents a draw-head, in which is secured a transverse shaft, B. The ends of this shaft are squared 'or angular,- as at b, and the central or intermediate portion,b, thereof is round. Collars O are secured on the angular ends of the shaft and have ratchet-teeth c in their 0 oosin faces. These collars are free to slide on the angular portions of the shaft, i but cannot rotate thereon. On the central i portion of the shaft is loosely journaled a. wheel, D, liaving peripheral projecting teeth (1, and on opposite sides of the said wheel are ratchetteeth d, adapted to engage with the teeth on the sliding collars O. Coiled springs E are placed on the. outer ends of the shaft B, and bear between the sides of the draw-head and the sliding collars, so as to keep the said collars normally in engagement with the wheel D. Levers F are connected to the sliding collars and pass up through slotted openings in the upper side of the draw-head. While the collars are in engagement with the wheel D the latter may be rotated in the direction indicated by the arrow in Fig. l, but cannot be turned in the opposite direction, as will be very readily understood.

G represents a draw-head attached to another car and having a pivoted link, H. When the cars come together, this link strikes against one of the teeth of the wheel D, and

partly rotates the said wheel, and is held in the notch between the said tooth and the one ad- Serial No. 192,023. (No model.)

1 jacent, and as the wheel D is prevented from turning in the reverse direction by the collars C the cars are firmly coupled together, as shown at Fig. 1, and the link is prevented from jumping up out of the notch when the cars are in motion by the upper side of the draw'head A. WVhen the upper ends of the levers F are moved toward eachiother, the collars are moved outwardly against the tension of the springs and disengaged from the wheel D, which is then free to turn on its shaft in the direction opposite the arrow in Fig. 1, and thereby disengages the link.

A car-coupling thus constructed is cheap and simple, and is not likely to get out of order, and is automatic in operation.

Having thus described my invention, I

claim 1. In acar-coupling, the combination of the shaft, the loose wheel thereon having the peripheral teeth, and the sliding collars engaging with the said wheel toprevent it from turning in one direction, substantially as described.

2. The combination, in a car-coupling, of the draw-head, the shaft, the wheel loose thereon and having the peripheral teeth and the ratchet-teeth on opposite sides, and the sliding collars having the ratchet-teeth to engage with the similar teeth of the wheel, for the purpose set forth, substantially as described.

3. The combination, in a car-coupling, of the link, the draw-head having the shaft, the wheel loose thereon and having the peripheral notches to receives one end of the link. and

the ratchet-teeth on opposite sides. the sliding collars having ratchet-teeth to engage with those of the wheel and look the latter to the shaft, and the lovers for moving the collars to engage or disengage the wheel, substantially as described.

In testimony thatl claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

HUGH WVALLAGE.
